Published Fresh light on the path to net zero



Researchers have used magnetic fields to reveal the mystery of how light particles split. Scientists are closer to giving the next generation of solar cells a powerful boost by integrating a process that could make the technology more efficient by breaking particles of light photons into small chunks.
Published 'Kink state' control may provide pathway to quantum electronics



The key to developing quantum electronics may have a few kinks. According to researchers, that's not a bad thing when it comes to the precise control needed to fabricate and operate such devices, including advanced sensors and lasers. The researchers fabricated a switch to turn on and off the presence of kink states, which are electrical conduction pathways at the edge of semiconducting materials.
Published Nitrogen emissions have a net cooling effect: But researchers warn against a climate solution



An international team of researchers has found that nitrogen emissions from fertilizers and fossil fuels have a net cooling effect on the climate. But they warn increasing atmospheric nitrogen has further damaging effects on the environment, calling for an urgent reduction in greenhouse gas emissions to halt global warming.
Published How molecular interactions make it possible to overcome the energy barrier



Non-reciprocal interactions allow the design of more efficient molecular systems. Scientists now propose a mechanism on how energy barriers in complex systems can be overcome. These findings can help to engineer molecular machines and to understand the self-organization of active matter.
Published Quantum sensor for the atomic world



In a scientific breakthrough, an international research team has developed a quantum sensor capable of detecting minute magnetic fields at the atomic length scale. This pioneering work realizes a long-held dream of scientists: an MRI-like tool for quantum materials.
Published Nonreciprocal interactions go nonlinear



Using two optically trapped glass nanoparticles, researchers observed a novel collective Non-Hermitian and nonlinear dynamic driven by nonreciprocal interactions. This contribution expands traditional optical levitation with tweezer arrays by incorporating the so called non-conservative interactions.
Published Solar absorption by black carbon in fire clouds quantified



Aerosol scientists quantify the extent of light absorption by black carbon in fire clouds to better model climate impacts of extreme wildfire events.
Published Great Salt Lake a significant source of greenhouse gas emissions



Newly announced research examining greenhouse gas emissions from the drying lake bed of Great Salt Lake, Utah, calculates that 4.1 million tons of carbon dioxide and other greenhouse gases were released in 2020. This research suggests that drying lake beds are an overlooked but potentially significant source of greenhouse gases, which may further increase due to climate change.
Published A recipe for zero-emissions fuel: Soda cans, seawater, and caffeine



Engineers discovered that when the aluminum in soda cans is purified and mixed with seawater, the solution produces hydrogen -- which can power an engine or fuel cell without generating carbon emissions. The reaction can be sped up by adding caffeine.
Published Better way to produce green hydrogen



Researchers have developed a material that shows a remarkable ability to convert sunlight and water into clean energy.
Published Tackling industrial emissions begins at the chemical reaction



Researchers are proposing a new way to curb industrial emissions, by tapping into the 'atomic intelligence' of liquid metals to deliver greener and more sustainable chemical reactions.
Published Spin qubits go trampolining



Researchers have developed somersaulting spin qubits for universal quantum logic. This achievement may enable efficient control of large semiconductor qubit arrays. The research group recently published their demonstration of hopping spins and somersaulting spins.
Published Seven steps to achieving the right to clean indoor air post-pandemic



Seven lessons learned from the COVID-19 pandemic about ventilation's crucial role in preventing the spread of airborne pathogens has been set out in a new article.
Published Researchers develop innovative battery recycling method



A research team is tackling the environmental issue of efficiently recycling lithium ion batteries amid their increasing use.
Published New groups of methane-producing organisms in Yellowstone



The team verified that microbes found in Yellowstone National Park hot springs produce methane to grow.
Published Study of urban moss raises concerns about lead levels in older Portland neighborhoods



Lead levels in moss are as much as 600 times higher in older Portland, Oregon, neighborhoods where lead-sheathed telecommunications cables were once used compared to lead levels in nearby rural areas, a new study of urban moss has found.
Published Warehousing industry increases health-harming pollutants, research shows



A new study shows an average 20-percent spike of nitrogen dioxide polluting the air for communities located near huge warehouses. And people of color are harder hit.
Published New study supports stable mantle chemistry dating back to Earth's early geologic history and over its prodigious evolution



A new analysis of rocks thought to be at least 2.5 billion years old helps clarify the chemical history of Earth's mantle -- the geologic layer beneath the planet's crust. The findings hone scientists' understanding of Earth's earliest geologic processes, and they provide new evidence in a decades-long scientific debate about the geologic history of Earth. Specifically, the results provide evidence that the oxidation state of the vast majority of Earth's mantle has remained stable through geologic time and has not undergone major transitions, contrary to what has been suggested previously by other researchers.
Published Trees reveal climate surprise -- bark removes methane from the atmosphere



Tree bark surfaces play an important role in removing methane gas from the atmosphere.
Published A new way to make element 116 opens the door to heavier atoms



Researchers have successfully made super-heavy element 116 using a beam of titanium-50. That milestone sets the team up to attempt making the heaviest element yet: 120.
